CVE-2022-42893
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability has been identified in syngo Dynamics (All versions < VA40G HF01). syngo Dynamics application server hosts a web service using an operation with improper write access control that could allow to write data in any folder accessible to the account assigned to the website’s application pool.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidencesyngo Dynamics application server hosts a web service with an operation that lacks proper write access control, allowing an authenticated or unauthenticated attacker to write data to any folder accessible to the web application's service account. This improper access control vulnerability enables arbitrary file write in locations reachable by the application pool identity.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Syngo Dynamics versionLocate and examine the installed Syngo Dynamics version on the application server - this is typically found in the product's about dialog, installer logs, or version information file in the installation directoryAffected if The installed version is lower than VA40G HF01 (for example, va40g or any earlier release)
-
Locate the vulnerable web service componentIdentify the Siemens Syngo Dynamics web service on the application server - check for the specific operation that handles file write operations, typically exposed through the application's web service endpoint configurationAffected if The web service operation lacking proper write access control is present and enabled on the system
-
Identify the application pool identityFind the service account used by the Syngo Dynamics application pool - this is configured in Internet Information Services (IIS) under the application pool identity settings or in the Windows service configuration for the Syngo Dynamics applicationAffected if The application runs under a service account that has elevated filesystem permissions
-
Review application pool account filesystem permissionsExamine the NTFS permissions granted to the application pool identity - check which directories the account can write to, particularly system directories and the web application rootAffected if The application pool identity has write access to directories beyond the intended application data folders, enabling arbitrary file placement
You are affected if your Syngo Dynamics version is earlier than VA40G HF01 AND the vulnerable web service operation is enabled AND the application pool identity has broad filesystem write access to locations outside authorized application directories.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpgrade syngo Dynamics to version VA40G HF01 or later to obtain the vendor patch. If immediate patching is not feasible, restrict the application pool account's filesystem permissions to only authorized directories and disable the vulnerable web service operation.
VA40G HF01
- 1. Identify the current version of syngo Dynamics installed on the system by checking the application server or consulting system documentation
- 2. Ensure you have a complete backup of all configurations, databases, and patient data before proceeding with any update
- 3. Obtain the VA40G HF01 update package from Siemens Healthineers through official channels (support portal or contact representative)
- 4. Schedule a maintenance window as updates to cardiovascular imaging systems may require downtime
- 5. Apply the VA40G HF01 update following Siemens Healthineers installation documentation specific to your deployment
- 6. Verify the update was successful by checking the application version shows VA40G HF01 or higher
- 7. Review that the web service operations now have proper write access controls implemented
- 8. Conduct functional testing to ensure the cardiovascular imaging system operates normally after the update
